A blog (a contraction of the term "Web log") is a Web site, usually maintained by an individual with regular entries of commentary, descriptions of events, or other material such as graphics or video. Entries are commonly displayed in reverse-chronological order. "Blog" can also be used as a verb, meaning to maintain or add content to a blog.

Many blogs provide commentary or news on a particular subject; others function as more personal online diaries. A typical blog combines text, images, and links to other blogs, Web pages, and other media related to its topic. The ability for readers to leave comments in an interactive format is an important part of many blogs. Most blogs are primarily textual, although some focus on art (artlog), photographs (photoblog), sketches (sketchblog), videos (vlog), music (MP3 blog), audio (podcasting), which are part of a wider network of social media. Micro-blogging is another type of blogging, one which consists of blogs with very short posts for example Twitter. See the Curriculum ICT tweets here

Typically, a blog "post" can be "commented" on by others, allowing for a dialogue on a the topic of the post. Teachers and educators have used blogs to allow for what is commonly called "peer review," meaning that students can post writings or assignments to the web, and other students can respond or encourage through the comment feature.

In a broader and more educational system, blogs are about communicating. You observe your experience, reflect on it, and then write about it. Other people read your reflections, respond from their perspectives by commenting or writing their own blog article. You read their perspectives, often learn something through their eyes, and write some more.
